A pre-trial conference for 41-year-old David Bennett was cancelled last week in Marion County District Court. The former Melcher-Dallas teacher accused of sexual abuse of a student is now set to appear in court next on April 20th, just two and a half weeks before his trial is set to begin. Bennett was arrested in January 2011 and charged with one count of second degree and one count of third degree sexual abuse. His trial date has been pushed back three times since being originally set for August of last year.
